What I Do

I am fascinated by morphology and evolution. In particular, my work has focused on the genomic and developmental mechanisms by which morphology and physiology evolve.  

Spatial biology. Developing new spatial -omic technologies for high-plex visualization of proteins and DNA loci.

Comparative genomics. Utilization of long read sequencing and genome scaffolding approaches to understand animal evolution and the evolution of genomes.

Lungless respiration. Studying the molecular adaptations that facilitate respiration in salamanders without lungs.

Lung development in lungless salamanders. What are the developmental and genetic mechanisms that account for lunglessness in salamanders? Most salamanders have undergone an evolutionary loss of lungs. There is little known about how such a loss is genetically or developmentally achieved.

Pleiotropic interactions between the lungs and heart in the development of the cardio-pulmonary system. Does lung loss have pleiotropic effects on the development of the heart? Despite clear circulatory changes that must accompany lung loss, there is little information on the associated changes to the heart and how these changes may be developmentally patterned.
